Abstract: Procédé d'obtention de pastilles d'oxydes frittées MxOy, M représentant un ou plusieurs des métaux ou éléments utilisés dans la constitution des pastilles combustibles nucléaires, incluant: a) le traitement d'une solution initiale de sels solubles du ou des éléments M à l'aide de peroxyde d'hydrogène, b) l'obtention d'un précipité de peroxydes en suspension dans des eaux mères, c) une séparation du précipité d'avec les eaux mères, d) une calcination, puis une réduction du précipité, conduisant à une poudre intermédiaire d'oxydes, et e) un pressage puis un frittage de la poudre. Le procédé permet d'obtenir directement des pastilles d'oxydes frittés de très forte densité supérieure à 95% de la densité théorique, tout en évitant des traitements particuliers de conditionnement des poudres intermédiaires d'oxydes. Dans ce procédé, le traitement a) de précipitation à l'aide de peroxyde d'hydrogène est effectué à partir des solutions concentrées des sels solubles à un pH maintenu entre 2 et 2,5 à l'aide d'ammoniac gazeux ou en solution dans un réacteur continu à lit fluide comportant au moins trois zones cylindriques superposées de section circulaire et de diamètres différents, reliées entre elle par des zones de jonctions tronconiques. Les trois zones cylindriques comportant une zone cylindrique d'extrémité base d'extraction du précipité, au moins une zone cylindrique centrale, dite de travail, au moins une zone cylindrique d'extrémité haute, dite de débordement, la zone d'extrémité basse ayant un diamètre inférieur à celui ou ceux de la ou des zones cylindriques centrales, la ou les zones centrales étant agitées vigoureusement tandis que l'agitation dans les zones d'extrémité est modérée.

Abstract: ABSTRACT OF THE DISCLOSURE       A collapsible framework comprises a plurality of spars pivotally connected with hub members.   The hub members comprise a first set which are disposed at the front of the framework when erected and a second get which are disposed at the rear of the erected framework, each of said spars being connected at one end with a hub member of the first set and at the opposite end with a hub member of the second set, and the spars being pivotally connected in pairs.  The arrangement is such that each hub member of the first set is opposite a respective hub member of the second set and moves nearer to its opposite hub member as the framework is moved from a collapsed to an erected state and moves further from its opposite hub member as the framework is moved from its collapsed to its erected state.  Opposite hub members of the first and second sets are connected by tension springs which assist in the unfolding and erection of the framework and provide  the  forces  necessary  to hold  the  frame  in  its erected position.  Vertical braces are detachably connect-able between the hub members after the framework has been erected to maintain the framework in position when loaded. These braces are themselves collapsible and are of iron or steel to allow cladding sheets having magnetic securing devices to be fitted to these vertical braces.

Title: Thermoplastic interpolymers and their use in mixtures of polyamide and styrene copolymers and/or graft polymers
Inventor: WESTEPPE UWE
IPC: C08G81/02
Filed: 1989-08-14
Granted: 1995-06-27
Abstract: The invention relates to thermoplastic interpolymers having a certain chemical composition and to their use in thermoplastic molding compounds of polyamides and styrene copolymers and/or graft polymers for the production of improved blends of polyamides and styrene copolymers and/or graft polymers, particularly ABS polymers, having homogen-eous surfaces and improved mechanical properties.   The interpolymers themselves are produced by compounding of polyamides and copolymers based on styrenes and/or acrylo-nitrile and/or (meth)acrylates with primary or secondary alcohols and at least one ester of (meth)acrylic acid with a tertiary C4-10 alcohol in the melt.  The interpolymers act as compatibility promoters in the blends and lead to a sur-prising improvement in a number of properties of thermo-plastic molding compounds.

Abstract: O Disclosed is a process whereby enzymes are immobilized on activated granular carbon. The process involves treating the carbon with a polyamine compound having pendant amino groups to cause the polyamine to adhere to the carbon leaving pendant amine groups free to further react. The free amine groups are derivatized by treatment with a difunctional compound having amine reactive moieties, so that free amine groups of the enzyme can be covalently bound to the polyamine via the amine reactive compound. By this method, enzymes can be immobilized onto granular carbon which provides a support having excellent physical properties.

Abstract: A pressure diffuser (10) for paper pulp includes a vertical pressurizable liquid-tight vessel (11) having a pulp inlet (12) at the bottom and a pulp outlet (13) at the top. One or more ring shaped screen elements (15), providing first and second concentric screen surfaces (16), are vertically mounted within the vessel. A number of radially extending header arms (18) mount the screen elements for movement in the vessel and in fluid communication with it. A first linear actuator (37) effects reciprocation of the arms. A cylinder (35), open at both ends, is affixed to the arms and extends both above and below them, and a piston (39) is disposed within the cylinder, below the arms. A second linear actuator (40) is operatively connected to the piston to effect reciprocation of the piston in the cylinder. A guiding conduit (46) surrounds the open end of the cylinder above the arms and guides reciprocation of the cylinder and transports liquid from the arms to an effluent outlet. A perforated jacket (57) surrounding the guiding conduit, nozzles (61) at the vessel wall, and the like introduce liquid into the vessel for treatment of the pulp. The ring shaped screen element is connected to the arms in a manner to allow the best liquid communication between them. In this way pulp can be effectively treated in a pressurized vessel while the screens for treating the pulp are periodically backflushed without causing a surge within the vessel.

Date Nov. 3, 1988.In the manufacture of an in-line cored pultruded profile, filler is bonded with polyester or methacrylate type resin and enclosed in fiberglass, carbon or aramid fiber cloth. The cloth is preformed to replicate the desired profile shape by means of a pre-die former and the external surface of a hollow duct. Filler is delivered into the interior of the duct by a variable output venturi blower. Precise distribution of packing is effected by the internal configuration of the duct and the creation of a raised moving wall when non-foaming resin is used. Precise configuration of ducts can be achieved by fashioning from reinforced cloth. Adjustable start drums provide time and labor saving benefits. Complete resin wet through using either foaming or non-foaming resin ensures exellent filler bonding and surface finish.
